From a84a7340b6291e209db2d5a3a28507816eec2223 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ky=C3=B6sti=20M=C3=A4lkki?= Date: Mon, 23 Sep 2019 10:01:16 +0300 Subject: [PATCH] sb/intel/bd8x62x,i82801gx: Fix PCI bridge subsystem IDs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implementation of ich_pci_dev_enable_resources() used to have a custom implementation to program PCI subsystem IDs for the (legacy) PCI bus bridge. With the local implementation removed, we no longer need the custom .enable_resources callback.
